Subject: perl plugin: Exported plugin_log() to Perl.
X-Git-Tag: collectd-4.0.0~81^2~1
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f59d051e2087090f15545c65facbc507699ac7e6;p=collectd.git

perl plugin: Exported plugin_log() to Perl.

This adds the following function to collectd's Perl API:

Collectd::plugin_log:
  pass a message to collectd's logging mechanism

  arguments:
  level - log level
  message - log message

The log level should be any of the Collectd::LOG_* constants.
